Tracked Vehicle Frame with Lateral Access Cutouts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tracked vehicle frames make it difficult to access and assemble components, such as the engine configuration, due to lateral extensions that obstruct access and prolong assembly time.
Innovation Solution
A vehicle frame design with a wedge-shaped extension frame that allows easy access by ending laterally at the level of the track assemblies, enabling the cab to tilt open and providing a single sealing plane for efficient assembly and protection, while reducing assembly time and facilitating component installation before track assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the vehicle frame has lateral extensions for structural support, then the structural strength is improved, but the accessibility to internal components deteriorates
Solution Approach 1:
The vehicle frame is divided into modular sections with removable panels. The lateral extensions are segmented into fixed structural portions and removable access panels, allowing the structure to maintain strength while providing accessible entry points to internal components when needed.
Solution Approach 2:
The lateral extensions incorporate removable or movable panels that can be opened or detached. This dynamic feature allows the frame to transition between a closed protective state and an open accessible state, resolving the contradiction between structural integrity and component accessibility.
2Stability of the object's composition
If the vehicle frame has complex structural portions for support, then the structural stability is improved, but the assembly time increases
Solution Approach 1:
The frame structure is divided into standardized modular sections that can be manufactured separately and assembled through simple connection mechanisms. This segmentation maintains structural stability while dramatically reducing assembly complexity and time.
Solution Approach 2:
Frame sections are pre-assembled and pre-positioned in the manufacturing process before final assembly. Critical structural portions are prepared in advance with pre-installed connection points, allowing rapid final assembly while maintaining structural integrity.
3Strength
If the vehicle frame extends laterally past the track assemblies, then the structural support is improved, but the ease of assembly deteriorates
Solution Approach 1:
The lateral extensions are designed as separate, extractable components that can be attached or removed independently from the main frame structure. This allows the core frame to be assembled without the extensions, simplifying the manufacturing process while maintaining structural support when extensions are installed.
Solution Approach 2:
The main frame structure is assembled to completion before attaching the lateral extensions. This preliminary assembly of the core structure allows for easier manufacturing and assembly, with the extensions added as final structural enhancements that provide support without complicating the primary assembly process.
